A new myth says volume buttons and mute switch on iPhone 4S are in a slighly different position, meaning current iPhone 4 cases does not fix, plus the supposedly fixed 4S antenna can not be used on the iPhone 4. Is this myth confirmed, plausibe or busted?
What about the compass? Is it integrated to GPS or is a dedicated IC?
Meh I would love to put a 3GS hardware inside a 1st gen aluminum case :D
